Find the Length of a Copper Wire 0

question 30

Short Answer

Find the length of a copper wire 0.104 inch in diameter if it has a resistance of 3.1 ohms ( 1 mil = 0.001 inch). Carry the answer to two decimal places. $$\begin{aligned}R = \frac { K L } { d ^ { 2 } } \quad \text { where } & R = \text { resistance in ohms } \\& L = \text { length in feet } \\& d = \text { diameter in mils } \\& K = 10.8 \text { (constant) }\end{aligned}$$
